On April 6, the Church of Jesus Christ of Latter-Day Saints is founded by Joseph Smith Jr. (1805-1844), in Fayette, New York. In Palmyra, New York, The Book of Mormon is published for the first time; Smith has translated it, he says, from golden tablets he found buried near Palmyra.

The first wagon trains to cross the Rocky Mountains arrived in California.

The U.S. Congress passes the Indian Removal Act.

The world's population tops 1,000,000,000 (it had been roughly 750 million only 50 years earlier).

1830

Painting by Eugène Delacroix: Liberty Leading the People (French: La Liberté guidant le peuple) commemorates the July Revolution of 1830, which toppled King Charles X of France. A woman personifying the concept and the Goddess of Liberty leads the people forward over a barricade and the bodies of the fallen, holding the flag of the French Revolution — the tricolour flag, which remains France's national flag — in one hand and brandishing a bayonetted musket with the other. The figure of Liberty is also viewed as a symbol of France and the French Republic known as Marianne. By the time Delacroix painted Liberty Leading the People, he was already the acknowledged leader of the Romantic school in French painting.

In Boston, William Lloyd Garrison founds the abolitionist newspaper, The Liberator, signaling a dramatic shift in the antislavery movement. In the previous decades, it had centered in the South and favored a combination of compensated emancipation and colonization of freed slaves back to Africa. In the 1830s, the abolitionist movement becomes the dominant voice among antislavery advocates. Abolitionists demand the immediate end to slavery, which they consider to be a moral evil, without compensation to slaveowners.

Nat Turner, a literate slave who believes he is chosen to be the Moses of his people, instigates a slave revolt in Virginia. He and his followers kill 57 whites, but the revolt is unsuccessful and up to 200 slaves are killed. After an intense debate, the Virginia legislature narrowly rejects a bill to emancipate Virginia's slaves. The widespread fear of slave revolts, compounded by the rise of abolitionism, leads legislatures across the South to increase the harshness of their slave codes. Also, expressions of anti-slavery sentiment are suppressed throughout the South through state and private censorship.

North Carolina enacts a statute that bans teaching enslaved people to read and write.

Slave Revolt: Virginia Slave preacher Nat Turner leads a two-day uprising against whites, killing about 60. Militiamen crush the revolt then spend two months searching for Turner, who is eventually caught and hanged. Enraged Southerners impose harsher restrictions on their slaves.

The first volume of La Dèmocracie en Amèrique (Democracy in America), by Alexis de Tocqueville (1805-1859), is published in France. Tocqueville, a historian and politician and member of the French aristocracy, writes about the American people and their institutions, based on his 9 months of travels through the United States and eastern Canada in 1831-1832.

1835

Painting by Caspar David Friedrich: The Stages of Life (German: Die Lebensstufen) is an allegorical oil painting completed just five years before his death. This picture, like many of his works, forms a meditation both on his own mortality and on the transience of life. The painting is set on a sea shore and shows in the foreground an aged man with his back turned to the viewer, walking towards two adults and two children on a hilltop overlooking a harbour. The figures are echoed by five ships shown in the harbour, each at a different distance from the shore, an allegorical reference to the different stages of human life, to the end of a journey, to the closeness of death. The figures have been identified as Friedrich and his family. The aged man is the artist himself, the small boy is his young son Gustav Adolf, the young girl is his daughter Agnes Adelheid, the older girl is his daughter Emma, and the man in the top hat is his nephew Johann Heinrich.}The Stages of Life (German: Die Lebensstufen) is an allegorical oil painting of 1835 by the German Romantic landscape painter Caspar David Friedrich.

1838

Daguerreotype by Louis Daguerre: The earliest reliably dated photograph of people, taken one spring morning in 1838 from the window of the Diorama, where Daguerre lived and worked. It bears the caption huit heure du matin (8 a.m.). Though it shows the busy Boulevard du Temple, the long exposure time (about ten or twelve minutes) meant that moving traffic cannot be seen; however, the bootblack and his customer at lower left remained still long enough to be distinctly visible. The building signage at the upper left shows that the image is laterally (left-right) reversed, as were most daguerreotypes.

La Amistad was a 19th-century two-masted schooner, owned by a Spaniard living in Cuba. It became renowned in July 1839 for a slave revolt by Mende captives, who had been enslaved in Sierra Leone, and were being transported from Havana, Cuba to their purchasers' plantations. The African captives took control of the ship, killing some of the crew and ordering the survivors to sail the ship to Africa. The Spanish survivors secretly maneuvered the ship north, and La Amistad was captured off the coast of Long Island by the brig USS Washington. The Mende and La Amistad were interned in Connecticut while federal court proceedings were undertaken for their disposition. The owners of the ship and Spanish government claimed the slaves as property; but the US had banned the African trade and argued that the Mende were legally free. Because of issues of ownership and jurisdiction, the case gained international attention. Former president John Quincy Adams argued on behalf of the slaves when the appeal was brought before the U.S. Supreme Court, which eventually determined the Africans to be free men. The case became a symbol in the United States in the movement to abolish slavery.

Louis-Jacques-Mandé Daguerre perfects and presents the daguerreotype process as the first publicly available photographic process (which for nearly twenty years was also the one most commonly used). To make the image, a daguerreotypist would polish a sheet of silver-plated copper to a mirror finish, treat it with fumes that made its surface light sensitive, expose it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; make the resulting latent image on it visible by fuming it with mercury vapor; remove its sensitivity to light by liquid chemical treatment, rinse and dry it, then seal the easily marred result behind glass in a protective enclosure.

John Herschel introduces hyposulfite of soda (now known as sodium thiosulfate but still nicknamed "hypo") as a highly effective fixer for all silver-based processes. He also makes the first glass negative.

Sarah Anne Bright creates a series of photograms, six of which are known to still exist. These are the earliest surviving photographic images created by a woman.

Although a bicycle consisting of a frame and wheels has existed for years, blacksmith Kirkpatrick MacMillan (1813-1878), introduces the first bicycle in its modern form, with brakes and pedals. The bike has iron tires and weighs nearly 60 pounds.

The first electric clock is built by physicist Carl August Steinheil (1801-1870).

In response to the British opium trade, Lin Zexu wrote a letter to Queen Victoria, urging her to end the opium trade: We find that your country is sixty or seventy thousand li from China. Yet there are barbarian ships that strive to come here for trade for the purpose of making a great profit. The wealth of China is used to profit the barbarians. That is to say, the great profit made by barbarians is all taken from the rightful share of China. By what right do they then in return use the poisonous drug to injure the Chinese people? Even though the barbarians may not necessarily intend to do us harm, yet in coveting profit to an extreme, they have no regard for injuring others. Let us ask, where is your conscience? The letter to the Queen never reached her. Belatedly, it was delivered and published in The Times of London.

Lin Zexu was a Chinese scholar-official of the Qing dynasty best known for his role in the First Opium War of 183942. In March 1839, Lin arrived in Guangdong Province to take measures that would eliminate the opium trade. He was a formidable bureaucrat known for his competence and high moral standards, with an imperial commission from the Daoguang Emperor to halt the illegal importation of opium by the British. Upon arrival, he made changes within a matter of months. He arrested more than 1,700 Chinese opium dealers and confiscated over 70,000 opium pipes. He initially attempted to get foreign companies to forfeit their opium stores in exchange for tea, but this ultimately failed. Lin resorted to using force in the western merchants' enclave. A month and a half later, the merchants gave up nearly 1.2 million kg (2.6 million pounds) of opium. Beginning 3 June 1839, 500 workers laboured for 23 days to destroy it, mixing the opium with lime and salt and throwing it into the sea outside of Humen Town. Lin composed an elegy apologising to the gods of the sea for polluting their realm.

The First Opium War between Britain and China occurs between 1839 and 1842, triggered when Chinese officials attempt to prevent the sale of narcotics (opium) to the Chinese people by the British East India trading Company. The British respond by bringing in gunboats and shelling Chinese coastal cities.

ESP Quick Facts

ESP Origins

In the early 1990's,
Robert Robbins
was a faculty member at Johns
Hopkins, where he directed the informatics core of GDB
— the human gene-mapping database of the international human
genome project. To share papers with colleagues around the world, he
set up a small paper-sharing section on his personal web page. This
small project evolved into The Electronic Scholarly
Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research
Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured
funding, through the ELSI component of the US Human Genome Project, to
create the original ESP.ORG web site, with the formal goal of
providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost
magical to the uninitiated, the original
techniques of classical genetics are readily appreciated by one and
all: cross individuals that differ in some inherited trait, collect
all of the progeny, score their attributes, and propose mechanisms
to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost
inexorably, into ever more complex models, until molecular explanations
begin to seem both necessary and natural. At that point, the tools
for understanding genome research are at hand. Assisting readers reach
this point was the original goal of The Electronic Scholarly Publishing
Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began
to use the site for their assigned readings. Other on-line
publishers, ranging from The New York Times to Nature
referenced ESP materials in their own publications. Nobel laureates
(e.g., Joshua Lederberg) regularly used the
site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals
were making their early content available in
digital format. As a result, ESP was obliged to digitize classic
literature before it could be made available. For many important
papers — such as
Mendel's original paper
or the
first genetic map
— ESP had to produce entirely new typeset versions of the works,
if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was
critically important for getting the ESP project on a firm foundation.
Since that funding ended (nearly 20 years ago), the project has been
operated as a purely volunteer effort.
Anyone wishing to assist in these efforts should send an
email to Robbins.
